Hello, I have found a small, hard bump on the side of my cat's head. I am fairly certain that it is new. It is not red, there is no broken skin and no sign of pus. It seems to be flesh coloured. It is hard. Any ideas on what it could be? Could it be a tick, if the tick actually got under the skin? He is an indoor only cat, but did live outside until October. He is about one year old, and otherwise in excellent health. No other symptoms. Thanks very much for any advice or ideas!
